1.4 RT engines...

[Anth1234]

Is there much to do to them? Apart from the ordinary air filter, exhaust system? (Super chip... which I don't really want to do)

I can't find much for them. I don't want a hugh increase in performance but I wanna hit at least triple figures, being 80 standard shouldn't be too hard... should it?

 

[edde]

Chris H (Ithink thats his username) on retro renault has one he has done porting bigger throttle body (from the 1.8 i think) and a few other bits.

80 to 100hp is a fair jump for NA its like taking a 2.0 172 up from 166.6 to 208hp and that as any proper tunner will tell you is expensive.

Value for money wise putting a bigger engine in is much much better value.

 

[Final Maxim]

1.8 laguna spi throttle body is what you want

 

[beatjunkie]

i agree with edde ive just had an energy lump rolling roaded, with a decat, full exhaust sys and relocation induction kit and got 84.4hp@91mph so bigger engine is a must mate if ya need more power!wouldnt waste your money on add-ons unless you only want noise!

 

[Final Maxim]

84.4, that aint too bad, book says theyre 75bhp standard, but they tend to go over the top, so youve definatly seen some decent gains.

what you hit in 1st n 2nd gear beat?

 

[beatjunkie]

dunno it dont list that!!ill post up the chart in a bit mate!!saw a crazy r5!!jumping all over the rollers!!torque at 87lbs/ft was good tho!

 

[Remedi]

^^I'd be happy with that bhp result.

Do you have the Hillpower IK?

 

[ajketley]

there is loads to do! If you spend the money

Gas Flow £300 +
Uprated cam £300 +
laguna spi trottle body (already said) £20 + (scrappy)
dastek piggyback ecu instead of just chipping it £400 +
Full system exhaust + decat
Either relocation or ramair induction kit

Then the things that you take for granted:

Uprated clutch
Suspension kit instead of springs
Uprated brake kit + uprated brake lines
Light weight alloys
Quickshift gear leaver
Front +rear strut braces
Poly suspension bushes + Uprated anti roll bar

List goes on and on...!

Depends how much you want to spend and what sort of car you want it to be!

Nick at hill power knows a few ways to get more power from them, give him a ring

 

[Jim_RT]

Re-profile cams from Piper for £150! Have a 4-2-1 manifold made up for around £300 also. Should go well with the gas flowed and ported head, etc.

 

[Maxx]

Try http://www.reichhard-motorsport.com/ for some harder to find parts. Bit of a pain as its German but good service.

Hi everyone,

Does anyone know which model Laguna has the spi throttle body? The only one ive found (1.8 8v) doesnt fit my 1.4 RT engine.

Also does anyone know if the 16v head from a Megane 1.4 16v will fit a clio E-series engine?

Cheers
Dan

 

[ajketley]

Dunno but dont think a 16v head will fit, why dont you just put a meggy engine in it? The laguna spi throttle body should fit if its the one thats on the top of the inlet mani (same as rt!)

Adam

 

[DanClio]

Because then il be paying for an engine swap on my insurance!!! which is about as much a williams to insure, even if it is a 1.4.

it's this throttle body (dont know where it goes) lol

Also do you know of any bigger manifold which fit the clio RT engines, e.g. laguna 1.8 spi mainfolds?

Dan

 

[ajketley]

Not really any but you can get one made up for around 300 quid.

Oh and that looks like a MPI throttle body. The SPI one looks near identical to your rt one!

Adam

 

[Fred@BTM]

bung a valver eninge in much easier

 

[DanClio]

That would be easier and cheaper (been qouted £700 for engine, head, loom, gearbox, exhaust, shocks, brakes and fitting) but try insuring it being 17.

Id say the modifed 1.4 engine will work out cheaper in the long run...even though it has no-where near the power of the 16v.

Where could i get a mainfold made???

Dan

 

[ajketley]

Again wouldnt know, try nick at hillpower, rung him today and he was very helpful, he may know!?

With insurance make sure you are in your own name! It makes sure you can get a faster car sooner

1.4 16v head won't fit as its completely different.

Headwork and cam will give a good gain and coupled with the 1.8 8v SPI TB from a laguna you'll get close to 100bhp.

You could also fit a 1.6 bottom end from a megane 8v (K7M engine)...it'll bolt straight on and give some extra power.

Bunging a 16v engine in would be a better base for more power but TBH i'd stick with the 1.4 lump...a good RT (with headwork, cam and TB) will give a std 16v a run for its money anyway. Also, with the RT engines, you've the added bonus of them being relatively bombproof by comparision, and lighter, and easier to work on, and cheaper to replace (like 40quid for an engine!) etc etc.

 

[Jim_RT]

Dan

I was speaking to John I think at Ashley Exhausts in order to have one developed and fitted, except my clutch is going in my car so that's knacked my plans. Really canny guy though and the price was roughly £300 to have it done. You'd see a nice gain in mid-range and that especially with a de-cat and good exhaust system.

 

[DanClio]

Cheers for that will give Ashley a ring see what they quote me at. I have the advantage of having a spare RT engine to work on so I can swap them over when the works done. Is there anything else I can do e.g. increase compression while the engine is out?

Does anyone know if the block of the RT engine is the same and the 1.6e (K7M) from the megane, just with a longer stroke?


Dan

Dan

Yes its the same and thats exactly how they got the capacity increase.

 

[DanClio]

Cheers mate,

So I could use the conrods and crankshaft from a 1.6 meggy engine, to make mine 1.6. Am I also right in assuming the head off of the 1.6e engine will fit on the 1.4e as it is the same block? Or is there no point in changing it?

Thanks for all your help by the way

Dan

 

[FincH]

If I had my 1.4RT and a bit of cash I'd do this:

Rebuilt K7M Bottom end on an early E7J head ported and polished by Chris H, Laguna 1.8 TB and a de-cat. Leave the rest of the engine and exhaust standard.

 

[u33db]

Dan

You could do it that way but thats rather pointless...better of just bolting a 1.6 BE on as is rather than swapping the parts over. It'll be in better nick anyway.

The head off a 1.6 should fit on a 1.4 block but the problem will be management...you'd likely need everything of the megane doner car which is a lot of hassle...i'd just stick with the 1.6 BE bolted to an early straight port 1.4 head

 

[DanClio]

Ok mate thanks for all your advice, One more question though.....renault made a 1.6 16v RT would this be the same block as the 1.6 and 1.4 energy??

Cheers mate

 

[u33db]

No, don't think so.

 

[FincH]

Oh just ignore me then...

 

[1fast6]

I'm currently in the process of gathering the parts necessary to increase the power of this engine on the cheap, no point pouring loads of cash into an engine so small.


Going for ported early head (Previously owned by Chris H so it makes the power), matched manifolds, laguna tb, magnecore leads and bosch super plus plugs, decat, s/s cat back, intake modification (using the stuff from the laguna engine coupled with a larger filter).

I'm expecting it to overfuel which is why i am trying to modifiy the air intake a bit to compensate and make the most of it. Also avoiding cams because they have to come from catcams or piper as special order so £300. Trying to keep this low budget.

If it reaches 100 that will be fantastic, realistically more like 90 but that will still be a substancial increase.

Unless you've got money to burn, don't bother paying tuners to work on it. The bill will end up being 600 quid or so probably more and its not worth it. Save your money and buy a valver. A good idea is to learn how to do all the work yourself or pay someone from here who knows what their doing to do the work.

 

[Anth1234]

So my list is;

1.6 bottom end from a megane 8v (K7M engine)
+ The block to go with the Bottom End (K7M)
+ My 1.4 RT Head
+1.8 8v SPI TB from a laguna
(any idea on how much this is going to all cost? or shall I just search and ask at scrapyards)

And all this will fit together nicely? My dad is a mechanic so no labour costs and an even easier job if it is an easy job : )

Am I going to have too re-map anything?

 

[1fast6]

Main thing about going that route, you are changing the displacement altogether. So you have to decide whether to declare that both to the dvla and to the insurance. You will have to find a decent 1.6e engine which means loads of messing about with scrap yards and hauling it back home. Not to mention they are sought after because of the straight swap. Then you may need to spend a couple hundred rebuilding it if necessary. The costs for these projects sprial quickly.

Don't put the head back on without getting it worked on. But yes it will all fit fine.

 

[u33db]

There not that saught after - a complete engine went on eay for about 75 a few weeks ago so going to a proper scrappy you'll find one for under 50. Straight swap yes but not many people will bother considering you can bang a 1.8/2ltr (8v or 16v) in for not much more...

 

[DanClio]

Anth...I bought a throttle body from my local scrappy for £30+vat and they wanted £50 for the bottom end of the megane K7M engine. They have 2 K7M's where I live if you wanted me to get one of them for you....Where abouts do you live?

Does anyone know where or who I can go to around the surrey area to get my head gas flowed or ported?

While im on the subject, which is better, gas flowing or port and polishing?
