applemobile 0 Posted March 14, 2008 i have th eide in my head to build a modestly priced 1.9 turbo engine ro put in my 1.6. i searched the site btw but cant find what i want to know. first of all, is it true the 2.0 8v turbo manifold will fit on the 1.9 head? i heard it will but with a little bit of re-angling. second question, has anyone done or seen of a twin webber/ bike carbs and turbo? i can immagine it would be a bit of a bitch to get running, but could be rather interesting.

danpug 1 Posted March 14, 2008 Yes the manifold bolts straight on. There are people who run carbs/turbo but i couldn't tell you anything about it, other than it'll drink stupid amounts of fuel! Share this post Link to post Share on other sites
applemobile 0 Posted March 14, 2008 cheers for that about the manifold. thats great news. im waiting for someone to tell me to just get the 2.0 8v. but i think its much nicer to have a powerfull engine that origionated from the car, rather than cheating and wacking in a bigger one. all tho im not against that at all!

danpug 1 Posted March 14, 2008 I was going to use the 2.0 turbo and manifold for my conversion but changed my mind in the end and went for a 205parts tt manifold. It would be handy for a budget conversion though, check out henry yorkes cti, he got good results. How are you lowering the compression? Share this post Link to post Share on other sites
205007 12 Posted March 14, 2008 shouldnt need to lower the comp unless you run massive boooooossssttt light pressure turbo should run ok btw renault 5 gt turbo runs carb and turbo Share this post Link to post Share on other sites
danpug 1 Posted March 14, 2008 That is true, obviously it depends on his plans. Share this post Link to post Share on other sites
applemobile 0 Posted March 14, 2008 well if i can get hold of a manifold i will use one, if not im sure i can build my own, not sure how long it will last tho! i have a contact that may beable to get the pistons machined down. but i feel weary of this. as surely you are making the pistons weaker, yet running more power. if its gonna cost to much i will just stick 2 head gaskets in for the time being. i dont want to run mega boost, but enough to get reasonable power. i know the r5 runs carbs and turbo, but it does not run twin carbs! the tecnologie is the same, i guess twin is going to be hard to set up and keep running correctly.

Tom Fenton 1,542 Posted March 14, 2008 Why on earth would you want to go to the hassle and grief of trying to blow through a pair of webers or similar! I'm quite sure that it will be a cheaper and far better solution to go for injection and a mappable ECU. This is what I'm doing with my XU5T project anyhow.

danpug 1 Posted March 14, 2008 Machined pistons are fine to use, Vern on here is/was running 240bhp ish on them. Two headgaskets is probably asking for more trouble tbh! I have a set of machined pistons/rods but they are from a 1.6, not sure if they are different from the 1.9 rods? Share this post Link to post Share on other sites

This is what I'm doing with my XU5T project anyhow. because i have a terriable addiction to unreliability, why else would i drive a 205? your probably right about the 2 headgaskets, i could get a spacer plate made, but teh cost would just be more worthwhile machiening down the pistons.

welshpug 1,661 Posted March 14, 2008 you could use 406 turbo engine management on it. Share this post Link to post Share on other sites
applemobile 0 Posted March 14, 2008 you could use 406 turbo engine management on it. o rly? please tell me more. is it a kinda plug and play operation. could i map it my self on my laptop? i would like to point out at this point that i am not a muppet, i do have mechanicle knowlege, its only that i work with big diesels, so do not get involved in all this dinky toy electricery.

welshpug 1,661 Posted March 14, 2008 I think its what henry runs his low compression turbo skip on. Share this post Link to post Share on other sites

TEKNOPUG 3 Posted March 17, 2008 You can get away with standard compression (it’s actually preferable for both performance and driveability) providing you use proper aftermarket management for fuel and sparks and have it mapped by someone who knows what they are doing. Should be able to run 10-14psi. So really, you need to think about this backwards – what management system am I going to use? Once you decide that then the mechanical side will easier as some paths will be closed to you and others will become a necessity, depending upon your initial ECU management decision.
