gt 4088 turbo

[Bob Monkhouse]

I am looking into buying this turbo with all the ancillaries for my fd, as soon as funds permit.
    Does anybody have advice on this turbo, price, horse power figures? (i have large extended ports on my fd, may have some more porting done at some point, full brige port or maybe monster port?) where to purchase these from, and also equivalent turbos?
   Cheers

Try www.rx7store they do it for 2000 dollars with all the ancelleries (cant spell). Don`t know how much they charge for international shipping and then there`s customs to worry about. Don`t know how laggy these turbos are but 500+ ponies should be a peice of pi**. Speak to blitzboy he`ll have more knolledge.

I bought my gt4088 from rx7store 5 months ago came my total bill was £2,500 but that was including other items duty was £103 I think delivery was around £75. I bought it with another member and the original del was £150 for 2 kits but this was reduced to £100.

The manifold is as kermin put it and ebay special. The gasket between the manifold  and the turbo failed (partly my fault as I fitted a new exhaust to reduce the noise and didn\'t fit one of the hangers correctly) and the oil feed line was way too long. Otherwise good kit full boost by 4K on large street, starts developing boost by 2k. Comes with screamer pipe that it very .... i think fun other say f**king loud.

Is your single a ballbearing type? What fuel injectors have you got?

i have seen them on the rx7store but never looked in detail. am i right in that the gt4088 is the ball bearing turbo, which was specially designed for racing applications and not just a truck turbo, and not the journal bearing turbo?
   I have also seen a gt4094? do these cost even more?!!
   As for loudness, i am not fussed however loud it is even if the neighbours do. Especially when me (Grant Monkhouse) and my dad have got another project in the back garden which is going to have a 13b PP in it, So i think brap brap loudness comes to mind.

500+ ponies at the wheels or flywheel?

Also would the two 1680cc injectors i have in my fd be more than enough for the larger turbo? personally i would want to stick another two in there just for fun, if possible.
  would a water and methanol injection get rid of lag, and obviously theintercooler?

[Bob Monkhouse]

Why don\'t you ask Carl dickhead? (Grants dad here peeps)!!!! And no, I\'m not going to take the intercooler out.Luv, Dad.

There is an online ebay shop selling the GT4088, I think the store name is GT3 turbos, I would keep the stock primaries, uprate the secondarys.

Water and meths will reduce detonation so you can run at a higher power without damage, it won\'t \'get rid of lag\', if the intercooler pipes are short and the correct bore, that will reduce the lag, as well as having a ported block.

Don\'t read about this turbo on piston based engines, a rotary produces a HUGE amount of exhaust from a smaller space, so can spool big big turbos

if you are talking or reducing lag and ditching the intercooler with water/meth, do you mean running pretubo?

Would it have to be? I dont know much about turbos and water/methanol injection, which is why i am asking for peoples advice.
I would normally ring and ask carl about stuff like this as he built my engine and mapped it, however he is a busy man and dont like to interupt him by ringing him up.
I am also better at taking information in by reading it than on the phone.

i only assumed that it would get rid of lag as the distance the air flow travel is reduced?? (Im learning loads here cheers)
What sort of PSI increases can you get by having water/methanol injection? Assuming this is what you mean by running at higher power?

there is a load of info on rx7club.com about running with water/meth, best bet is to trawl through it all. with regards to running preturbo, there still appears to be a bit of conjecture about what it does and does not do, I am planning on running it once my car is rebuilt, i will elt you know how i get on! in the meantime if you want to send me PMs asking questions then feel free, i admit i dont know all the answers, but i might no where you can find them!
